Optus and Huawei trial 4.5G

22 February 2016 |


Optus and Huawei have announced a trial of 4.5G, resulting in download speeds of 1.41Gbps, reaching theoretical maximum speeds of 1.43Gbps.

The trial which took place at Optus’ Gigasite in Newcastle, Sydney saw a combination of carrier aggregation, higher level modulation and 4X4 MIMO achieving a peak download speed of 1.23Gbps over the air in live network conditions. 

“We continue to utilise our network and spectrum assets to test our network of the future and prepare for 5G. By 2020, 5G will be here and we are committed to identify ways to prepare our network to support this new technology and further improve customer experience,” said Dennis Wong, acting managing director of Optus Networks.

James Zhao, CEO of Huawei Australia said the trial is a “first and important milestone” as a result of its investments in R&D in Australia. 

Both parties first began their collaboration in 2013 with the announcement of Optus’ Gigasite trial, what it claimed then to be the world’s largest mobile broadband site throughput of 2.3Gbps. TeliaS

Separately on the eve of Mobile World Congress 2016, Huawei has announced multiple strategic cooperation on the development of 4.5G with operators including TeliaSonera, HKT, LG Uplus, P4 and Viva.  

At MWC’s 4.5G Industry Summit, Ryan Ding, president of products and solutions, noted the vendor’s focus on the three core concepts of 4.5G: Gbps, Experience 4.0, and Connection+.

“Telecoms operators should never cease their innovative efforts during the evolution to 5G if they want to occupy a prominent position in the market. These innovation efforts are the essence of what drives and motivates the 4.5G technology,” said Ding.

“4.5G allows operators to deploy NB-IoT, broadband trunking, and additional new technologies to existing networks. This enables operators to fully maximise advantageous latent potential to better serve vertical markets," he added.
